Description

Ship structure production design process for smart factory implementation {SHIP STRUCTURE MANUFACTURING AND DESIGN PROCESS FOR REALIZING SMART FACTORY}

The present invention relates to a ship structure production design process, and more specifically, to remove a design change factor due to production conditions at the site, and transmit DB-designed information to the production site without creating a separate design drawing, an intelligent ship production plant. It relates to a ship structure production design process for implementing a smart factory, which can be implemented.

In general, the conventional ship structure production design process combines and takes into account various prior information received in the form of a hard copy in the early stage, the capacity and assembly method of the factory determined before design, and reflects them in modeling by considering them and produces them based on this. Feedback to technology and prior design (structural detail design and chairman design) and then reflected again to complete the final structural production design modeling and simultaneously deliver two types of information: drawing and data.

This process is a process that the designer reflects and verifies in modeling by hand, which implies the possibility of modeling rework and errors, which causes the quality of structural production design to deteriorate.

On the other hand, as shown in Figure 1, the ship structure production design process as described above, basically, a step of creating a block and establishing a production plan and establishing a reference plan for establishing a design schedule (S10), the basic The step (S20) of receiving the preliminary information of the design (structural design and design of the design) and production technology in a hard copy form (S20), and conducting structural production design modeling for each block and finding errors during modeling input to the preceding department Feedback information and consultation and reflecting prior information Handwriting input step (S30), tree analysis (tree analysis) for inputting assembly sequence and transmission line, and production method for inputting bevel information considering processing line and method for modeling Step (S40), and a program for extracting information about the hull member defined using shipbuilding-specific three-dimensional modeling software such as tri-bon or AM, for example, DWP (DaeWoo Ppanparts) ; Modeling information extraction and storage step of extracting information input to modeling by in-house PGM that extracts information about the hull members defined using the tri-bone modeling program and storing it in the HiBS (Hull information data Bank System) DB ( S50), and an auto-nesting program, for example, DPN (DSME Plate auto-Nesting; PGM) to create a process drawing and assembly drawing and online drawing verification step quality (S60), and work drawing It consists of an on-site transmission step (S70) of delivering an assembly drawing and transmitting the design data of the HiBS DB to the integrated production system.

However, in the ship construction production design process according to the prior art, there is a risk that quality problems due to input errors occur due to handwriting input by the designer and receiving prior design information in the form of a hard copy. When a design modification occurs due to a change, it is necessary to go through a complicated work step of design information transmission, reception, reflection, and feedback, so there is not a small number of rework occurrences, and there is a problem that the design reflection time is lengthened.
